Propionyl-L-carnitine-(N-methyl-d₃) chloride (CAS: 1334532-19-2) is a deuterium-labeled version of propionyl-L-carnitine, where three hydrogen atoms in the N-methyl group are replaced with deuterium. This labeling makes it a useful internal standard for mass spectrometry (GC-MS or LC-MS) in metabolic research and clinical diagnostics.
Key Features:
- Isotopic Labeling: The deuterium label allows clear differentiation from natural propionyl-L-carnitine in mass spectrometry.
- Accurate Quantification: Serves as a reliable internal standard for precise measurement of propionyl-L-carnitine levels.
Applications:
- Metabolic Research: Used in studies on fatty acid metabolism and β-oxidation of odd-chain fatty acids.
- Clinical Diagnostics: Helps assess carnitine levels in diagnosing metabolic disorders.
How to Use:
- Storage: Store at -20°C, protected from light and moisture.
- Solubility: Easily dissolves in solvents like DMSO, DMF, and ethanol for analytical procedures.
Propionyl-L-carnitine-(N-methyl-d₃) is an essential tool for researchers studying metabolism, fatty acid oxidation, and related clinical conditions.
